2. In the free choice test, consumption and acceptance of the bait were compared to the consumption of an active-ingredient-free, coarse bait recommended by the U. S. Environmental Protection Agency (EPA) and composed of 55 % corn-groats, 35 % oat-flakes, 5 % sugar and 5 % sunflower oil. In the free choice feeding trials the rodents received the bait and the poison-free food, in addition to drinking water, ad libitum or for a limited time, i. e. 24, 48, 72 or 96 hours. The toxicity of the rodenticide was assessed on the basis of bait ingestion (preference %) as compared to the alternative food, and the mortality rate. In the free choice feeding trials the two foods were offered from two feeding boxes placed in the cages symmetrically. To eliminate any error resulting from habituation, the two foods were exchanged every 24 hours. The animals received fresh test materials every day. The consumed amount was determined and the time of death was recorded as described in the toxicity tests. |yVv| LANIRAT (BÁBOLNA) with 5% sugar LANIRAT (BÁBOLNA) without sugar I j LANIRAT (CIBA-GEIGY) Fig. 3: Comparative appetibility test of LANIRAT baits manufactured by the Bábolna Bioenvironmental Centre, Budapest and by CIBA-GEIGY
